To all whom, it may concern,.-

l Beit known that I, ALBERT E. DIETERICH,

residing at Washington,in the District of Columbia, have invented certain new and useiul Improvements in Electric VVater-Purifiers, of which the following is a specification.

' My invention 'relates -to certain new and useful improvements in electrical water-purifyng' alpparatus in which water is puriiied by e ectro ytic action in the presence o1 aluminium electrodes.. Y" In its genericnature my invention includes a casing, a pai'of aluminium electrodes held therein in thegform ofv a spiral screw and means for rotating said screw at times to tus without removing the electrodes.

In-Aits more .detailed 4nature the invention i, comprises' certain novel construction, 'coin- Vbination, and arrangement of parts, all of 3o which will be irst described in detail and thenbe specifically pointed out in the appended claims, reference being had to the accompanying drawings, inwhiche 1' is a face view of my invention. Fig. 2 is a vertical longitudinal section thereof on line 2 2 of Fig. 1, the electrodes bein shown in elevation. Fig. 3 is a detaile ,cross-section taken substantially on theline fainting2.L y 4:.

- Referring now to the accompanying drawings, in which like numerals of reference indicate like partsin all of the figures, 1 designates a base of: any. suitable material upon which the outer casing 2 is mounted by means of lugs2bandscrews2c,as shown. Thecasing 2 is screw-threaded at itsu per and lower ends to receive the caps 6 an 4, respectively, which are held water-tight on the casing by means ofthe washers 7 and 5, respectively, and each of the caps 6 and 4 is provided with seats 6a and 4a, respectively, to receive the central stem 11, of vitreous or other insulating material, which stem 11 is provided with the double spiral electrodes 12 and 13,

respectively, which electrodes are uminium and magnesium and are spaced sufliciently apart to permit passage of thewaspiral passages between the electrodes. In practice I may place the electrodes 12 and 13 casing 2 than at the bottom for a purpose run the entire length of the casing,but termiupper chamber between the electro es and the presently understood.

brushes 12a 135, which contact with the con- '.tact-rings 8 and 9, respectively, to which the positivefand negative terminals 15 and 16 for the usual purpose.

3 designates .the inlet-spout pipe, which spout or end of t e casing to permit water being withdrawn from the apparatus. i

The central stem 11 of the electrodes has a continuation 'which passes through a gland 6b in the cap 6 and receives a turn-wheel 14, as shown. i ,1

my invention operates will be best ex lained 3, iills the chamber 2a and passes up through the casing in a spiral direction between the electrodes 12 and 13 and out through the outlet-spout 10. As the water passes between electrodes 12 and 13 the same will be under the influence of the electric current, and the imerstood in the art, the preci itate will accumulate in the chamber 2, ut can be removed at any time by simply removing the cap 4. Should any precipitate accumulate on .the

or stem 1 1 by means of thehand-wheel 14, and the impurities will be unscrewed l and ejected into the chamber 2, romwhic'h'they can be removed in the usualmanner.

-1 As before mentioned, practice I may space the electrodes closer to ether at the top and gradually separateth'em toward the botreferably' constructed of aluminium or an a loyof al.

closer together at the top or outlet end of the nate short of the ends thereof to rovide an' i The electrodes 12 and 13 have contact.

So far as described .the manner in which"j 'as follows: The water enters throught e pipe electrodes, it is only necessary to turn the core ter through the casing from end to end in the r presently understood. The electrodes do not v cap 6 and a lower chamber 2a for a purpose.V

ation, an

tom until they are spaced apart their greatest distance at the inlet end of the apparatus, for this reason, namely, that as the Water enters the apparatus through the pipe 3 it isinv an impure state, and hence a goo conductor of electricity. The electric current will pass easily between the positive and negative electrodes; but as the water becomes purified its conductivity decreases in proportion to the removal of the impurities therein, it being well understood that chemically-pure Water Now as the water is urer and purer toward the top or outlet eng of the apparatus the conductivit decreases proportionately and therefore 1t may be of advantage to place the electrodes closer together at the outlet end of the apparatus. This, however, I do not consider as an essential adjustment of the electrodes in my apparatus, as it may be found advisable to space the same an equal distance apart throughout the entire length.

From the foregoing description, taken in connection with the accompanying drawings, itis thought the complete construction, operd numerous advantages of my invention will be readily understood by those skilled in the art to which it appertains.
